Frequently Asked Questions
What is the function of an elastomer?
An elastomer is a synthetic elastic material, used for O-ring seals to provide bubble-tight shut-off in a valve and prevent leakage. Typical materials are Viton, Buna-N and EPDM (ethylene propylene monomer).
What is the internal pressure relief?
It is a self-relieving functionality in non-independent seating valves that automatically relieves excessive internal body pressure caused by sudden changes in line pressures. By using the piston effect principle, the excessive body pressure will move the seat away from its seating surface and relieve it to the lower pressure side.
What is the function of the valve operator?
It is a device that converts manual, hydraulic, pneumatic or electrical energy into mechanical motion to open or close a valve.
